"l3e it known that l, GEORGE F. Giaveno, a citizen of' the United States, residing at of' Colorado, have'invented certain new and -This"invention relates to hydro-carbon burners and its object resides in providing a burner of very simple construction which can be readily installed in the fire chamber of an ordinary kitchen range, which is easily cleaned Without being removed from the stove and which by substantially complete combustion of the carbon will burn crude oil, commonly known as distillate;7 Without vSmoke or odor.l

`An embodiment of my invention has been illustrated in the accompanying drawings in the various views of which like parts 'are similarly designated, and in which, Figure l is a plan. vieuT of my improve burner, Fig. 2, a longitudinal section taken along the line 2 2 Fig. 1, showing thev burner in its operative position in the tire chamber of a kitchen range, liig. 5, a trans-1 verse sectiontalren alongI the line SW3 Fig.

' 1, Fig. 4, an enlarged sectional view of a portion or' the vaporizing chamber of the burner, Fig. 5, a transverse section taken along the line 5 Fig. 4l. v

Referring to the drawings by numerical reference characters, 2 designates the base of `the burner, which is provided at its front with an upright support 3 to' which is attached by` means of screws l, distance sleeve 5 and a sheet metal plate d which, When the device is installed in the lire chamber of a kitchen stove, occupies the opening in the front of the same formerly closed byv the lire door. Formed integrally 'upon the base plate is a mixing chamber 7 composed. of an inverted U-shaped 4conduit 8 the ends of `which have in the under surface ofthe plate, air-inlet ports 9. mixing chamber has in the top of its horizontal bodyportion intermediate of its downwardly bent ends, a passage 10 for the outward flow of the combustible mixture, and belon7 the same an opening l), for the passage of oil into a priming pan 13 which formed upon 'the upper surface ci? the base by an upwardly Droioctine rib 1d.

through the horizontal. portion of the miciu 111g chamber and throughalined openingsl in the support 3, and the plate 6, is a vapor' pipe 15 which by` means of elbows 16 is at one of its ends connected with a pipe 17 which extends over the conduit 8 in parallel relation to its horizontal portion and which constitutes the vaporizing chamber of the burner. The vaporV feed` pipe 15 is at its outer end which is the end opposite to that at which it 'connects with the vaporizing chamber, closed by means of a screw cap 18 and it has in alinement with the passage 10 of the mixing chamber, a small aperture 19 for the escape of vapor.. The screw/cap 18 is .enlarged at its outer end to provide a hand-Wheel which facilitates its removal and replacement Without the use of tools when the burner is being cleaned. The pipe 17 which like the pipe 15 extends through openings in thevsupport 3 and the plate 6, is at its end opposite to that at which it connects with the vapor feed pipe, attached by means of a reduction coupling 2G to a pipe 21 which exteriorly` of the stove, connects 'with an elevated oil reservoirY not shown in the drawings. i valve mounted in the coupling is provided to control the liow'of liquid from the pipe 21 into the vaporizing chamber 17. A core 23 composed of a bunch of Wires 2l tied together by a surrounding spirally Wound Wire 25, occupies the interior of the pipe 17 and is provided with a handle Q6 to permit of its ready removal after the coupling has been detached. The primary object of this core is to provide a spiral passae throue'h which the oil introduced into,

the vaporizing chamber past the valve 22,

lions, ,thereby retarding its progress through the chamber andpermitting every part of the liquidto come in directcontact with the surface oi' the pipe 17 which is heated by the vapor burning in the combustion space p Q7 between the mixing chamber andl the v."aporizing chamber. The Wires of which the core is composed are preferably made of .copper by reason ci its heat retaining properties and after the core has been thoroughly V heated it aids in vaporizing the oil flowingv spirally valong its exterior surface. another result of the provision of the core is the prevention of backward movement of the oil by the vapor pressure in the feed pipe7 which porizing pipe With a source of fuel supply, and a removable means closing the exterior end ot' the .vapor-feed pipe.

6. A hydro-carbon burner comprising aplate adapted to occupy an opening in the side of aA stove in whose lire-chamber the burner is installed, a vaporizing pipe and .a therewith connected apertured vapor feedpipe projecting through openings in the said plate, means for connecting the exterior portion ot the vaporizing pipe with a source of fuel supply, and a removable means closing the exterior end of the feed-pipe.

7. The combination with the lire-chamber of a stove, of a hydrocarbon burner ineluding a vaporizing pipe `and an apertured vapor-feed pipe connected within the re chamber and projecting at their nnconnected ends exteriorly of the fire-chamber, de-v tachable means for connecting the exterior end of the vaporizing pipe with a source of fuel supply, a removable means closing the exterior end ofthe vapor-'feed pipe, and an exteriorly channeled core loosely disposed within the vaporizing pipe for removal Copies of this patent may be obtained oithrough its exterior end lafter the means which connect the saidpipe. with the source` of fuel-supply have been detached.

8. A hydrocarbon burner comprising a plate adapted. to occupy an opening in the side of a'stove in whose tire-chamber the burner is installed, a vaporizing pipe and a therewith connected apertured vaporrfeed pipe projecting through openings in the said plate, detachable means for connecting the exterior portion of the vaporizing pipe with a source ot uel'supply.y a removable means closing the exterior end ofthe teed-pipe,and an exteriorl)1 channeled Core looselv disposed within the vaporizing pipe, for removal through its exterior end after the means which connect the said pipe with the source of fuel suppbv have been detached.

In testimony whereof I have affixed my signature in presence of tvvo witnesses.
